Description

This is a visible (RGB) orthomosaic derived from UAV imagery via Structure from Motion processing. UAV flights were performed in Sunny conditions on September 25th, 2019, collecting RGB images using the built-in camera on a DJI Mavic 2 Pro. The raw imagery had an approximately 3cm ground sample distance (GSD). Images were processed in Agisoft Metashape Software (version 1.6) to derive a georeferenced dense point cloud and 3D model. Images were orthorectified and combined into a mosaic using the 3D model. This dataset has been georeferenced using 14 ground-control points, but has not been radiometrically calibrated.
